Weird bug with this mod installed, spawns a lot of mobs around the player in ocean once the player uses a egg spawner.

Only performance mods installed.
Steps to reproduce:

1. Install forge 43.3.2.
2. Install mods shown + Cupboard(it's not in the picture).
3. Create new world.
4. Go to nearest ocean or big water body.
5. Use any Spawner Egg.
   It should instantly spawn a ton of squids and fish around the player.

I also should mention that it makes the world generation hang a lot while first generating, have to wait at least 2-3 minutes for entire chunks to appear and I don't think it's because of my pc, I have 32GB of ram with ryzen 7 5800x.
